WICHITA, Kan., U.S. - 2014年4月24日 - INVISTA and Solvay have signed a settlement agreement that resolves disputes related to adiponitrile (ADN) intellectual property and technology in use at their nylon 6,6 intermediates Butachimie joint venture in Chalampé, France.

The settlement confirms INVISTA’s exclusive ownership of the ADN technology at Butachimie and includes a plan to upgrade the facility with INVISTA’s latest and most advanced ADN technology. The planned upgrade would be one of several components in a new joint venture relationship between the two companies.

“Retrofitting Butachimie with INVISTA’s newest ADN technology will dramatically increase the plant’s efficiency,” said Warren Primeaux, president of INVISTA Intermediates. “Under this new joint venture, we are excited to work together with Solvay to better serve our customers and support nylon 6,6 growth.”

The Butachimie joint venture has been operating for 40 years, and is the world’s largest ADN facility. The nylon 6,6 intermediates made at Butachimie are used to make nylon 6,6 fibers and polymers that ultimately become part of air bags, automobile parts, carpet, workout apparel, outdoor equipment and more.
